Communication protocol 119 - 140
But the setting range of “running command channel” is 0~2, if it is set to 3, because the number is beyond
the range, the inverter will return fault response message as below:
Abnormal response code 86H means the abnormal response to writing command 06H; the fault code is 04H.
In the table above, its name is operation failed and its meaning is that the parameter setting in parameter
writing is invalid. For example, the function input terminal can not be set repeatedly.
7.5 Example of writing and reading
Refer to section 7.3 for the command format.
7.5.1 Example of reading command 03H
Example 1: read the state word 1 of the inverter with the address of 01H (refer to table 1). From the table 1,
the parameter address of the state word 1 of the inverter is 2100H.
RTU mode:
The command sent to the inverter:
If the response message is as below:
ASCII mode:
The command sent to the inverter:
If the response message is as below:
The data content is 0003H. From the table 1, the inverter stops.
7.5.2 Example of writing command 06H
Example 1: make the inverter with the address of 03H to run forward. See table 1, the address of
“communication control command” is 2000H and forward running is 0001. See the table below.
